<li class="listitem"><p><code class="classname">GdaFieldAttributes</code> has been renamed <code class="classname">GdaColumn</code></p></li>
<li class="listitem"><p>The <code class="classname">GdaParameter</code> is now an object, and it is extensively used within 
	    <code class="classname">GdaParameterList</code> objects. Each <code class="classname">GdaParameterList</code> object represent a 
	    vector of parameters (which may or may not have values assigned) and is the base of the
	    <code class="classname">GdaDataModelIter</code> iterator object. The <code class="classname">GdaParameter</code> API has been
	    altered.</p></li>
<li class="listitem"><p>The <code class="classname">GdaExport</code> class has been removed, the features it offered are now implemented
	    in each <code class="classname">GdaDataModel</code> object.</p></li>
<li class="listitem"><p><code class="classname">GdaSelect</code> has been renamed 
	    <code class="classname">GdaDataModelFilterSQL</code></p></li>
<li class="listitem"><p>The <code class="classname">GdaTable</code> class has been replaced by the
	    <code class="classname">GdaDataModelQuery</code> class: it's a data model which can refresh itself and can be
	    configured to be updatable, it's not limited to a database table.</p></li>
<li class="listitem"><p>The <code class="classname">GdaXmlDatabase</code> has been removed and the default database is now SQLite
	    which is a complete RDBMS in a file</p></li>
<li class="listitem"><p>All the <code class="function">gda_xql_*()</code> functions have been removed because they were unused and unmaintained.
	  </p></li>
<li class="listitem"><p>The 'xml' provider has been removed as it did not work correctly and has been replaced by the SQLite provider
	    as the provider to have serverless databases.</p></li>
